摘要
针对武汉市城市森林的抽样调查分析表明,城市树木树种构成集聚性明显而多样性相对较差、长势一般;城市扰动因素明显影响了树木的自然生长过程。在所调查的93种植物中,其总体多样性指数为0.727 8;行道绿地为0.187;公园绿地为4.296。结果表明武汉市城市森林的基本格局、树种结构,以及树种分布上均有待于改善。
Based on the investigation and analyses of the urban forest in Wuhan, the composition of tree species was agglomerative distribution, and the diversity was relatively poor and the condition of growth was mediocre moderate. The city disturbance obviously influenced the process of tree growth. 93 species plants were found in the investigation, their index of diversity was 0.727 8 in gross, the road-greenbelt of them 0. 187 and the park greenland 4. 296. The analyzing results showed that the basic pattem, tree species structure and tree species distribution of the urban forest in Wuhan needed to be improved.
